During the Horus Heresy the Death Guards Space Marines joined the rebel Warmaster Horus and took part in many battles against forces loyal to the Emperor. Mortarion, Primarch of the Death Guards, turned to the worship of Nurgle, Lord of Decay, after the entire Legion became trapped in the warp and was ravaged by plague. Mortarion's fevered ravings were answered by Nurgle who saved the Death Guards and made Mortarion his Champion. Subsequently Mortarion led his Space Marines on a merry dance of destruction over a score of planets. Following the death of Horus and the effective end of the Heresy, Mortarion fled with the rotting remnants of his Space Marines into the Eye of Terror. There he received Nurgle's ultimate reward and rules the Plague Planet as the Daemon Prince Mortarion.

Mortarion is a cowled, skeletal figure wrapped in tattered robes which flap in an ethereal, pestilent breeze. He bears a daemon-etched scythe to reap the souls of the living. In the first fire segment of the combat phase Mortarion can invoke a Plague Wind, the winds around him suddenly rising to a howling blast which echoes with maniacal laughter. Choose any enemy model within 15cm. This model is infected with a deadly rotting disease and must make a saving throw to survive (models which don't normally have a saving throw save against the Plague Wind on a 6+). If the model fails it is destroyed and you can pick aonther model within 15cm of the rotting remains which must also make a saving throw to survive. The Plague Wind will continue to take effect until a model makes a saving throw or the last victim dies with no other models within 15cm.
